Lumbra raises $25 million Series A to run AI agents on secure intelligence networks

Lumbra raised $25 million in Series A funding to develop AI agents for sensitive computing environments, according to SiliconANGLE. Point72 Ventures and Ansa Capital led the round, with participation from Costanoa.

The startup's LumbraOS platform manages AI agents across proprietary and open-weight models. Its Nebula component traces agent claims to source data, StarChart connects information across datasets with sensitivity tags, and Astrolabe applies governance policies and monitors agent performance.

SiliconANGLE reports that Lumbra's agents were operating on a top-secret defense network within six months of securing a contract with an unnamed US intelligence agency. The Pentagon later named Lumbra as one of two companies underpinning its Agent Network project.

The company will use the funding to expand its engineering and product teams, increase sales activity, and target organizations in healthcare, finance, and law.
